7Installing Power Supply Units
The power supply unit (PSU) is a hot swappable field replaceable unit and can be replaced while
the router is operating as long as the remaining (second) PSU is installed and in operation (with 220V
power input). The AC and DC PSU follow the same steps for installation. The PSU comes pre-
installed and the following are instructions on how to install a new PSU.
If power input for AC power supply is only 110V, there will only be 1000 watts per power
supply and will not be enough power for the power supply to be changed while the router is
in operation. In order for AC power supply to be changed while the router is in operation,
ensure that 220V power is supplied.

8Grounding the Router
It is recommended that equipment changes be done on a grounded rack system. This will reduce
or prevent the risk of shock hazards, equipment damage, and potential of data corruption.
The router can be grounded from the router's case and/or the power supply units (PSUs). When
grounding the PSUs, ensure that both PSUs are grounded at the same time in case one of them is
removed. A grounding lug and M4 screws and washers are provided with the package contents,
however, the grounding wire is not included. The location for securing the grounding lug is at the
rear of the case and is covered with a protective label.
The following instructions are for installing the grounding lug onto the case.
This equipment must be grounded. Do not defeat the ground conductor or
operate the equipment without correctly grounding the equipment. If there is any
uncertainty about the integrity of the equipment's grounding, please contact the
electrical inspection authority or a certified electrician.
1. Before grounding the router, ensure that the rack is properly grounded and in compliance with
local regulatory guidelines. Ensure that there is nothing that can obstruct the connection for
grounding and remove any paint or materials that may prevent good grounding contact.
2. Strip the insulation from a size #6 AWG grounding wire (not provided within the package
contents), leaving 1.125”+/-0.02” (28.6+/-0.5mm) of exposed grounding wire.
3. Insert the exposed grounding wire all the way into the hole of the grounding lug (provided with
package contents).
4. Using a crimping tool, firmly secure the grounding wire to the grounding lug.
Figure 19.

S9705-48D Hardware Installation Guide | 17
5. Locate the designated location for securing the grounding lug, which is located on the rear of
the router and remove the protective label.
Figure 20.
6. Using 2 M4 screws and 4 washers (provided with the package contents), firmly lock the
grounding lug to the designated grounding location on the router.
Figure 21.

9Connecting Power
DC Version
1. Ensure there is enough power to supply the system.
The maximum system power consumption is 1466 watts. It is recommended to ensure that
enough power is reserved from the power distribution system before installation. Also, please
ensure that both PSUs have been properly installed before powering up the equipment, as the
S9705-48D is designed to support 1 + 1 power redundancy.
2. Attach the DC power cables to the lugs.
The UL 1015, #6 AWG DC power cable (not provided) must be attached to a two-hole lug
before connecting to the PSU. The following instructions are for connecting the DC Power
Cable to the lug:
2.1 Strip the insulation from a DC Power Cable, leaving 0.5” +/-0.02” (12.7mm +/-0.5mm) of
exposed cable
2.2 Insert the exposed DC power cable into the heat shrink tubing, the length of heat shrink
tubing should not less than 38.5mm.
2.3 Insert the exposed DC power cable all the way into the hollow tube of the lug (provided
with the package contents).
2.4 Usinga crimping tool, firmly secure the DC power cable to the lug. It is recommended to not
crimp exceeding the lines indicated on the lug, which is also depicted as the cross-section area
in the picture on the below.
